Abstract: A color measurement method performs a color measurement in which an influence of a fluorescent brightening age included in a printed form is corrected. With respect to the influence of the fluorescent brightening age, a measurement is performed only on a white portion of the printed form. With respect to the color patches constituting a color chart, a correction is performed by a correction quantity in which a reference correction quantity for correcting the influence of the white portion is weighted.

Abstract: An exemplary fishing lure evaluation system includes a light transmission element, such a red-free green filter of 50% transmissivity, arranged relative to a light source for illuminating the lure under evaluation primarily with light transmitted through the element so as to reproduce the natural underwater illumination for the lure including the effects of the water coloration and the light level preference of the type of fish targeted. Preferably, a viewing element is included through which the lure is observed, such as a clear lens or red-free green filter of 50% transmissivity, to duplicate the effects of the water between the fishing lure and the fish for a nominal presentation distance. Specific forms of the invention include an assortment of filters for use with a conventional flashlight or, alternatively, a lightweight plastic tube having, for example, red-free green sides, an open end and a clear condensing lens at the opposite end to reproduce the primary winter feeding conditions for steelhead or salmon for short or long presentation distances depending on whether the user views the lure through the lens or the sides, respectively. The system permits evaluation of all types of lures including homemade lures, fluorescent lures and multicolored lures. A standard proven effective for the local fish population, such a natural food specimen, can be used to select a color attractive to this population, or the system can be used to grade the lures according to how well they hold their apparent color when observed with the system.

Abstract: An imaging system includes a light source configured to illuminate a target and a camera configured to image light responsively emitted from the target and reflected from a spatial light modulator (SLM). The imaging system is configured to generate high-resolution, hyperspectral images of the target. The SLM includes a refractive layer that is chromatically dispersive and that has a refractive index that is controllable. The refractive index of the refractive layer can be controlled to vary according to a gradient such that light reflected from the SLM is chromatically dispersed and spectrographic information about the target can be captured using the camera. Such a system could be operated confocally, e.g., by incorporating a micromirror device configured to control a spatial pattern of illumination of the target and to modulate the transmission of light from the target to the camera via the SLM according to a corresponding spatial pattern.

Abstract: An apparatus for imaging a tooth having a light source with a first spectral range and a second spectral range. A polarizing beamsplitter (18) light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor (68), wherein the first and second polarization states are orthogonal. A first lens (22) in the return path directs image-bearing light from the tooth, through the polarizing beamsplitter (18), toward the sensor (68), and obtains image data from the redirected portion of the light having the second polarization state. A long-pass filter (15) in the return path attenuates light in the second spectral range. Control logic enables the sensor to obtain either the reflectance image or the fluorescence image.

Abstract: A reference-color measurement step of obtaining a reference-color measurement value by measuring a spectroscopic-radiation luminance of a light being emitted from a reference-color portion in a measurement direction, or a tristimulus value thereof, using a light-source-color measuring instrument 5, without irradiating the reference-color portion with a light source for measurement, in a predetermined measurement environment; an objective-portion measurement step of obtaining an objective-portion measurement value by measuring a spectroscopic-radiation luminance of a light being emitted from a measurement-objective portion in the measurement direction, or a tristimulus value thereof, using the light-source-color measuring instrument 5, without irradiating the measurement-objective portion with a light source for measurement, in the measurement environment; and a color identification step of finding a color of the measurement-objective portion by means of computation from a ratio of the objective-portion measurement value with respect to the reference-color measurement value are equipped. Even when measuring a color of such a body, like a body including a fluorescent material, whose reflectivity has changed depending on the type of light source, it is possible to measure the color of such a body accurately.

Abstract: A method for outputting a closest match of a plurality of electronically stored shade guide values of a dental shade guide system is disclosed. A protective tip including a hole for couples light from a probe to a measurement spot on a dental object. The probe is in proximity to a reference standard and a calibration/normalization measurement of the reference standard is taken. Light returned from the dental object is measured with an optical sensor. A first frequency proportional to an intensity of a first wavelength/spectral band of light is determined, a second frequency proportional to an intensity of a second wavelength/spectral band is determined, and a third frequency proportional to an intensity of a third wavelength/spectral band of light is determined. A closest match is selected of a plurality of electronically stored shade guide values of one or more dental shade guide systems.

Abstract: The measuring device comprises a lighting system, a photoelectric receiver unit and optical means. The lighting system applies light to image elements disposed in strip-shaped lighting regions (15) at a standardized angle of incidence range. The photoelectric receiver unit comprises several photoelectric line sensors (21) disposed parallel at a distance apart which are sensitized to different wavelength ranges by color filters (22) connected upstream. The optical means comprise linear optical arrays (31) which pick up the measurement light reflected by the image elements at a standardized range of angle of reflection and direct it to one of the respective line sensors (21). By means of optical screening and other structural features, cross-talk effects between adjacent image elements are largely reduced.

Abstract: A scanning device for photoelectrically measuring a measurement object in the form of a printed sheet on the basis of image elements comprises a measuring table (MT) for supporting the measurement object, a measuring device which can be moved above the surface of the measuring tables for scanning image element lines of the measurement object, a drive system for moving the measuring device above the measurement object, a measurement and drive control system for the measuring device and drive system, and a processing unit, for processing and evaluating the measurement signals generated by the measuring device from the scanned image elements of the measurement object (S). The measuring device comprises a lighting system, a photoelectric receiver unit and optical means. The lighting system applies light to image elements disposed in strip-shaped lighting regions (15) at a standardized angle of incidence range. The photoelectric receiver unit comprises several photoelectric line sensors (21) disposed parallel at a distance apart which are sensitized to different wavelength ranges by color filters (22) connected upstream. The optical means comprise linear optical arrays (31) which pick up the measurement light reflected by the image elements at a standardized range of angle of reflection and direct it to one of the respective line sensors (21). By means of optical screening and other structural features, cross-talk effects between adjacent image elements are largely reduced.The scanning device enables the entire printed sheet to be scanned at high speed and is relatively uncomplicated in terms of its construction. It combines the advantages of technologies known from imaging technologies but without their intrinsic disadvantages. It is suitable for quality control applications in the graphics industry and for the calorimetric control of printing processes.
